Generalized additive models in plant ecology

WebNov 30, 2002 · Generalized additive models The identification of appropriate polynomial terms and transformations of the predictors to improve the fit of a linear model can be tedious and imprecise. The introduction of models that automatically identify appropriate transformations was a second important step forward in regression analyses. WebJan 19, 2024 · Our main target is to show how these tools develop models based on regressions, and explore the advantages and disadvantages of each model. The second aim is to compare these models and decide which is the most accurate according to easily understood indicators.
